Rolle, is the same guy who talked his buddy to go to the Giants saying they're a great team - while he was on the Bears roster.
The practice facility at HH is actually the Walter Payton center. It's been called by many many players one of the best in-door practice facilities in the NFL.
I've been there many times. My kid played a touch football game there with McCown once.
Funny, no one I ever saw slipped just walking. If he did in fact blow up his knee that way, then I say couldn't have happened to a more deserving guy.
Fuck you Rolle. And if some sorry ass team decides to roster you this year, here's to hoping you blow up your other knee.
